Obviously not a sport - just a game First, I give credit that you need very good skills to play the game of bowling consistently well. I like bowling and it's fun.
But saying that, when you can be completely out of shape and still bowl a perfect game, the peak achievement of the "sport", it's embarrassing to call that a sport. Please do not ever say it's a sport because of a 16lb ball (way less then 10% most bowlers body weight). Just don't. Even so, if someone can still bowl a perfect game with a lighter ball, that makes it even more embarrassing to make the argument that the ball is heavy. A skinny 10 year old boy has bowled a perfect game! Is he that much stronger and more athlete than you? And for god's sake, this is a game with no variables either. It's you, a flat lane and the same number of pins all the time.
Don't even try It's extremely weak to justify billiards as a sport by comparing it to hunting with guns, darts or other games like that. None of these are sports. Here should be a litmus test for you: If you can be completely fat and out shape and be one of the top "athletes" of a sport [pause for laughing to stop], then for god' sake that's not a sport. Do not embarrass yourself. It's game, and I admit very tough to be good at, but still only a game and not a sport. Next you gonna say that poker is a sport? They play that on ESPN so it must a be sport! Just because something is tough to be good at, it does not make it a sport.
And, I am not a jock by any means, I am just being reasonable and stating the obvious.
